Have you tried to configure mailman to use exim -odqs ?

This reduces load sometimes, running nscd helps you to reduce the time a
process needs for resolving the mx (not much, but better than nothing).

split_spool_directory helps to reduce running times of processes too,
because you don't get "Message locked" messages all the time.
